Why I built PC Bottleneck Test: a free CPU & GPU bottleneck checker

Hey Product Hunt! 👋

I built PC Bottleneck Test because I kept seeing the same question in PC-building threads: "Will my CPU bottleneck my GPU?" Most answers were guesses, and the existing calculators felt either cluttered or too generic.

What it does:

• Pick your CPU, GPU and resolution

• See an estimate of the CPU vs GPU balance

• Get upgrade ideas so you know what to change first

It's free, and I'm adding more CPU/GPU pairings and improving accuracy based on feedback.

A caveat: any bottleneck calculator gives an estimate, not a guarantee. Real results depend on the game, settings and your other components.

I'd love your help with two things:

1. Which CPU/GPU combos should I add or check next?

2. Did the result match what you see on your own PC?

Thanks for checking it out. pc bottleneck test

I'll be here all day answering questions!
